In this paper

a new hybrid filter algorithm based on triangle modulus fusion operator was proposed to overcome the shortcomings of the hybrid linear and nonlinear filter techniques.Based on the properties of competition

complementation and redundancy of information fusion

this algorithm makes fusion decision about the boundary point using the triangle modulus operator

then performs hybrid filtering based on the fusion results.This new algorithm can overcome the shortcomings of the decision with single source

i.e.

high error risk

low reliability and fault tolerance

therefore improve the filter performance very well.The following experiments demonstrate the validity of this new algorithm and prove that it provides a novel approach for image filter technology.
